Its in general, im a part reseller and have the doubt about that, if i could do the same whit the ddr2 modules that do with ddr1 , so depend of the board then ? if the board only suppor 533mhz and i use a 667mhz the board se the mem like 533mhz ?
If your mobo is rated for DDR2 800 and you supply it with DDR2 533 it will POST at 533, like I said it defaults to the most conservative value to guarantee operation initially. I think that is the point you were after.
No, it wasnt. Its about using higher rated RAM than the motherboards standard.
I'm not sure what are the problems that would arose since generally DDR2 <1000 uses high voltages, and of course, high speeds.
Most DDR2-800 is programmed as DDR2-533 or DDR2-667. Same goes for faster varieties. This stuff is all overclocked at it's brand-rated speed, and requires manual configuration anyway.
There's a "new technology" that can make the nonstandard adjustments for you, called EPP or SLI-Memory. It's only an extended value, added to SPD, that tells the motherboard what voltage is needed to overclock the memory to a certain speed.
Niether. SPD values for "performance modules" are arbitrarily assigned by the manufacturer in hopes that they'll be slow enough for your system to boot, whereafter you enter BIOS to raise the voltage so that when you set the "advertised" values you can still reboot.
